In a world where emotion is deadly, one girl's courage to feel may ignite a revolution.

Gavril follows the rules. Don't dream. Don't imagine a better future. Don't cross the barrier, and whatever you do, don't open your heart to emotions-especially the most powerful one: love.

Breaking the rules is deadly. Phases surround Gavril's rural, impoverished village of Nostalgie. These mysterious ethereal beings, attracted to human emotion, suck passion and soul from anyone they touch-if the victim survives the encounter. Despite the danger, demanding questions linger in Gavril's heart. What might life be like beyond the electrical barrier keeping the Phases at bay? What happened to her father, a legendary Résonateur gifted with the ability to combat Phases, who vanished several years ago? What does freedom feel like?

When the Solenoid powering the village's barrier begins to die, Nostalgie's mayor offers Gavril's hand in marriage to the son of a nobleman in the distant village of Envie-a woman of a Résonateur bloodline to raise the family's prominence in exchange for a new Solenoid. Gavril has no choice but to comply. If she refuses, the barrier will fall.

Gavril will do anything to save her mother and fellow villagers-even if it means breaking a few rules.

Led by a heart that suppressed curiosity and compassion for far too long, Gavril befriends a Phase named Morrow. When her actions are discovered, she is deemed a traitor by her future in-laws and sent to the Capital, Éthéré Coeur, for judgement. Commandant Serein, a Résonateur like her father, escorts her to her destiny.

In the whirlwind of French-influenced, retro-futuristic adventure that follows, Gavril's spirit is freed. She meets wonders of human achievement-from motorized automatrams and flying soulevers to massive electronic libraries holding the world's secrets. She encounters the rich, vibrant, and sometimes horrifying world beyond Nostalgie . . . and she falls in love.

Once you break the rules, where do you draw the line?

Ghost of Nostalgia will resonate with readers drawn to rich worldbuilding, emotional rebellion, and character-driven dystopian fantasy. For fans of lyrical prose, slow-burn tension, and stories that challenge what it means to feel-this journey lingers long after the final page.
